Ancient World Mapping Center. (Online)
"The Ancient World Mapping Center exists to promote cartography and geographic information science as essential disciplines within the field of ancient studies. The Home page communicates knowledge of, and enthusiasm for, its subject." With support from the National Endowment for the Humanities (2006-2007), the Ancient World Mapping Center has undertaken a major initiative to develop a functioning, international community of scholars, teachers, students and enthusiasts to collaborate in the updating and expansion of the spatial and historical reference information assembled by the Classical Atlas Project. To underpin these efforts, the Center is developing a web-based, multi-lingual, spatially-enabled community support system, built using open-source software and made freely available for reuse by other projects.
